To all lw/i'om z' may concer/n.'

Be it known that I, FRANK B. CoMrNs, a citizen of the United States,residing at Newton, in the county of Middlesex and State ofMassachusetts, have invented new and useful Improvements in Nozzles, ofwhich the following is a specification, reference being had to theaccompanying drawings, forming part thereof.

This invention has reference to improvements in that class of nozzlesadapted to deliver water to the atmosphere for the purpose of cooling ortreating thc water by subjecting the same to the free action of the alr.

One object of the invention is to provide a.nozzle adapted to. assist inthe distribution of water issuing therefrom as a spreading sheet and toavoid undue rotary action of the water after it leaves the nozzle.

Other objects of the invention will appear from the followingdescription.

The invention consists in the improved nozzle as shallhereinafter bemore fully described and pointed out in the claim.

Figure l, represents a longitudinal sectional view of the improvednozzle.

Fig. 2, represents-a cross 4sectional view of the same taken on line 2 2Fig. 1.

Fig. 3, represents a detail sectional view of the nozzle member forcontrolling certain action of the water -within the nozzle.

Similar characters of reference demg'nate corresponding partsthroughout.

In carrying this invention into practice I construct a nozzle comprisingthe shell 5 having the screw threaded bore 6, constituting the inlet,the chamber 7 contracted at one end to the collar 8 which has an innerthread to receive the member 9 whichvhas the outlet bore 10 flared atboth ends.

The inner wall of shell 5 adjacent the bore 6 preferably is parallel toreceive the `plug member 11 which has the series of passages 12, 12which are inclined to the axis of this plug and are arranged around thecentral chamber 13 the area of which is considerably greater than thearea of any one of the passages 12, 12. Through the Wall of the upperend of said chamber 13 is formed a series of curved slots or oriiices14, 14 the radius of the curves of which coincides with the wall of saidchamber 13.

When water under suitable pressure is supplied to the nozzle through thebore 6 the chamber 13 is filled with such water which then passesthrough the orifices 14, 14 and reaches the chamber -7 substantially asan annular stream havinga diameter greater than the bore 10. The greaterportion of the water thus supplied through 'the bore 6 passes throughthe inclined passages l12, 12 whereby this portion of the Water isdirected in a tangential direction as it enters the chamber 7 whereby avortex is created in said chamber of which the annular stream suppliedto the chamber 7 through the ori- Iices 14, 14 may be considered thewall although, as a matter of. fact, said annular stream mingles ormerges with the embracing centrifugal body of water and tends to pushforward said body of Water through the outlet bore 10. As the combinedbodies of water reach said bore 10 the pressure exerted by the straightannular stream, from orifices 14, 14, tends to resist the centripetalaction of the swirling body of water passing through such contractedoutlet with the result that as the water issues from said bore 10 itspreads laterally as a comparatively thin sheet or sheets of water whichis particularly subject4 to the action of air.

In actual practice I nd that the chamber 13 is desirable as by its use abody of water,

is maintained, as a supply immediately at the orifices 14, 14, which isnot influenced` by water passing into the passagesr 12, 12.

Having thus described my invention I claim as new and desire to secureby' Letters Patent- A nozzle comprising a shell having an inlet and anoutlet and a chamber, the wall of which is cylindrical adjacent saidinlet end FRANK BfcomNss,
